Question

我正在尝试上传用户的个人资料头像。我想做的是将用户图片上传到/ assets，并将路径存储在我的表“用户”中的“头像”字段下。因此，我阅读了在线codeigniter教程，但无法弄清某些方面。首先，在我看来，该表单用于上传图片：

 <div class="profile-img">
                        <img class = "rounded-corners" src="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcS52y5aInsxSm31CvHOFHWujqUx_wWTS9iM6s7BAm21oEN_RiGoog" alt="profile image"/>
                        <div class="file btn btn-lg btn-primary">
                        Change photo
                        <?php echo form_open_multipart('pages/do_upload');?>
                            <input type="file" name="avatar"/>
                            <input type="submit" value="upload"/>
                        </div>
                    </div>

，然后在codeigniter教程中创建了控制器：

public function do_upload()
{
    $config['upload_path'] = './assets';
    $config['allowed_types'] = 'gif|jpg|png'; 
    $config['max_size'] = 100;
    $config['max_width'] = 1024; 
    $config['max_height'] = 768;

    $this->load->library('upload', $config); 

    $data = array('upload_data' => $this->upload->data());

    $this->load->view('profie', $data);

}

但是我什至无法上传图片到文件夹中……而且，我必须考虑一个好主意，将我要上传的图片重命名并将路径存储在列的表中……但是我d想至少上传图片开始

个人资料视图：

<div class="container emp-profile">
        <form method="post">
            <div class="row">
                <div class="col-md-4">
                    <div class="profile-img">
                        <img class = "rounded-corners" src="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcS52y5aInsxSm31CvHOFHWujqUx_wWTS9iM6s7BAm21oEN_RiGoog" alt="profile image"/>
                        <div class="file btn btn-lg btn-primary">
                        Change photo
                        <?php echo form_open_multipart('pages/do_upload');?>
                            <input type="file" name="avatar"/>
                            <input type="submit" value="upload"/>
                        </div>
                    </div>
                </div>
                <div class="col-md-6">

@TimBrownlaw 我再次检查了我的代码和所有内容...现在这是我的观点：更改照片这是我的控制器：

public function do_upload()
{
    $config['upload_path'] = 'uploads/';
    $config['allowed_types'] = 'gif|jpg|png'; 
    $config['max_size'] = 10000;
    $config['max_width'] = 1024; 
    $config['max_height'] = 768;

    $this->load->library('upload', $config); 

    $data = array('upload_data' => $this->upload->data());
    var_dump($data);
    $this->load->view('profile', $data);

 }

现在我收到此消息：“上载路径似乎无效。”但是根据我的计算机，我有权限...这可能是与docker或lamp服务器有关的问题吗？我认为这与写权限有关，因为这里的这段代码一直在说我的目录不可写。

<?php if(is_writable(base_url('uploads'))){
echo 'writable';
}
 else { echo  (base_url('uploads'). ' ' ."is not writable");} ?>

我显然尝试过chmod 777“目录”，并且根据我的mac，我获得了读写许可。但是无法上传该死的照片。可以和码头工人的灯箱设置相关吗？
